CTOS

The ctOS is the brainchild of Blume Corporation. After it's creation, the ctOS was handed over to the government by Blume in the wake of a major blackout across the American Northeast in 2003.

ctOS is Chicago's Central Operating System which regulates all manner of electronics within the city, from surveillance cameras to traffic lights. It is run by major private companies who use it for their own gains. It records and stores every part of a person's life and in turn figures out how one thinks.

Aiden Pearce has full access to the ctOS and can control any part of it. He can control video cameras, traffic lights, trains, and bridges. He can also disrupt connections between other cell phones.
